Qt Creator and other tools

For the one's complement C++ has its own operator

quint8 hexval_1_complement = ~15; // 11110000(2) 240(10) F0(16)
quint8 hexval_2_complement = ~0x15; // 11101010(2) 234(10) EA(16)
[/quote]

Thank you, I understand!
Cheers for the examples as well, well appreciated.

That "Pretty much" solved my problem! I get the right values and answers now.
But I'v been trying to achieve this using variables.

eg
Your push a number in.. stick with 15..that is saved to a variable (An integer)

Int Number= 15;
quint8 hexval_2_complement = ~0x(Number);

That is invalid and does not work (Being Int shouldnt affect?, but replacing with 15 will produce 234, thus can be converted to EA.

I CAN do
quint8 hexval_1_complement = ~Number; // 11110000(2) 240(10) F0(16)

But as noted above it produces 240, which isn't exactly helpful.

Sounds weird to obtain the int value then use that val as the hex val (as they dont equal each other).

lrelease creates translations in the QM file only for the strings that are marked as "finished".

Did you use Qt Linguist to translate your strings? Sorry to ask, but that wasn't clear in your post...

If not, you might want to check :
"Qt Linguist Manual for Translators":http://developer.qt.nokia.com/doc/qt-4.8/linguist-translators.html
and
"Qt Linguist Manual for Release Manager":http://developer.qt.nokia.com/doc/qt-4.8/linguist-manager.html

Thanks! Filing "a bug report":http://bugreports.qt.nokia.com/ once you found a way to reproduce the issue would be appreciated.

Hi,

this is not the first question regarding this topic in this forum.
The answer is: you will know when it is out.

Until now, there was never another answer from the Qt team.

I have built Qt 4.7.4 successfully on OpenIndiana using gcc 4.5.1. IIRC I have some issues trying to compile with the Sun Compiler Suite. In any case you will need to specify -no-webkit (and potentially -no-script) to configure to get it to build.

Is there really a qmake in /Developer/Tools/Qt? Isen't that usually in a bin subfolder on the Mac? I am no expert there;-)

thanks a lot, it worked. I was just messed up with the Quotes

Yeah, it is Ctrl-Tab/Ctrl-Shift-Tab... I should have looked it up to make sure before writing this. I use it so often that I am not even sure anymore what the exact key-combos are.

Try touching *.ui files and then cleaning the project.

Make (which is used to decide which parts of the code need to be rebuild) is based on timestamps on the files. If you had your system clock screwed up once that can cause some interesting issues with stuff not getting rebuild properly:-)

Hi Andre!

First of all, thanks for your extensive and quick support.

Sure, I know about the way binaries and libraries in C/C++ work, hence it is clear to me that I cannot build a Windows MinGW (or MSVC) widget and use that in a non-Windows Qt application.

But, of course, what I CAN do is building C/C++ applications for a specific hardware/OS target and use libraries therein, which are equally built for the same target. That is actually what C/C++ is all about. But here comes the trick with cross-compiling: Both libraries and binaries created (for the same target) are completely independent from the host environment (setting aside the fact, that I need an appropriate toolchain with all includes, binaries, libraries, tools and the like available, which are required for cross-compilation).

But as you mentioned, I need a Qt Creator IDE which is built with the same (!) toolchain as the widget plugin is built with to make it available to the Qt Designer. Of course, I could cross-compile without using the designer - that would make me independent from the host system (as for plain C/C++ development) as required, but neglect the advantage of sort of WYSIWYG development.

But probably you're right: In the end, Qt is C/C++ and requires at least basic knowledge of what's going on there - particularly if you want someone to develop for a more "exotic" purpose like cross-compiling for QNX.

Nevertheless, thanks for all your support.

Stupid error:
@# ==== Keep console in debug ====
contains(MODE, debug) {
CONFIG += console
}
contains(MODE, release) {
CONFIG -= console
}@

Thanks Volker - that helps!

Hi Tobias,

After installing QtCreator latest version my Qt 4.8 system installation was not detected on OS X Lion.

I think QtCreator user preferences got corrupted by the update process.

I did not file a bug report for that.

I see, thank you for explanation Tobias.

Ok guys, thats what I expected.

Too bad it would be really cool to integrate the online documentation with its new features into the QtCreator.
Maybe it will be possible in the future.

Thanks for your reply...

Thank you very much.
This worked perfect when I used the qm file.

Well that sounds helpful. Thank you :)

Ok! I will watch that bug-report link to see what happens.
